摘要

Axisymmetric thermal flows in porous media are a complex phenomenon that can be effectively studied using computational methods. In the current study, a new OpenFOAM solver is carried out to investigate this field. The Brinkman–Forchheimer extended Darcy model is used and implemented in the used solver. The new solver is validated through several benchmark problems. A great agreement is observed between the current study results and the analytical solutions and/or results from previous studies. Additionally, the impact of the Forchheimer term on the velocity profile is examined in the first two cases. Next, the effects of a few nondimensional parameters are discussed, such as the porosity and the Darcy number, for the case of a conduit that is partially filled with porous structure. Their influence on the axial velocity distribution is also explored. The results demonstrated the effectiveness of the new solver in investigating the porous media problems.
